13. Indicadores ambientais na avaliação de efluentes de truta arco-íris (Oncorhynchus mykiss) criados em sistema de raceway através do fósforo e nitrogênio
Resumo A descarga de fósforo e nitrogênio via efluente do sistema intensivo de truticultura foi quantificada através da utilização de indicadores ambientais. As cargas de nutrientes, o balanço de massa, a quantidade estimada de nutrientes na ração e a quantidade de nutrientes convertidos em biomassa de peixes foram calculados com base nas concentraç

14. Expressão da enzima indoleamina-2,3-dioxigenase em truta arco-íris (Oncorhynchus mykiss)
Resumo: A indoleamina 2,3-dioxigenase (IDO) é uma enzima que cataboliza o aminoácido triptofano, levando à inibição da proliferação de linfócitos T, seja pela exaustão desse aminoácido no ambiente, ou pela indução via catabólitos induzindo-os a apoptose. Em mamíferos, esta enzima atua em diversas condições do organismo como a gestação, infe

15. Rendimentos do processamento e composição química de truta arco-íris (Oncorhynchus mykiss) em relação ao peso corporal
O objetivo deste trabalho foi analisar a influência da categoria de peso (CP) da truta arco-íris sobre o rendimento do processamento e a composição centesimal do peixe inteiro eviscerado e do filé. O delineamento foi inteiramente casualizado para as variáveis do processamento (CP1 = 300 a 370 g e CP2 = 371 a 440 g) e em esquema fatorial 2 x 2 para comp

16. Comparison of fatty acid content of fresh and frozen fillets of rainbow trout (Oncorhynchus mykiss) Walbaum
The aim of this study was to evaluate and compare the percentage content of fatty acids (FA) of 54 rainbow trout fresh and frozen fillets. Frozen fillets were stored at -15ºC for 45 and 90 days. Saturated (SFA), monounsaturated (MUFA), polyunsaturated (PUFA), omega-6 (n-6) and omega-3 (n-3) fatty acids were determined by gas chromatograph coupled to mass sp

17. Extração e caracterização de óleos de resíduos de peixes de água doce / Extraction and characterization of freshwater fish waste oils
This study aimed to: (1) evaluate the performance and physicochemical characteristics of viscera oils from rainbow trout (Oncorhynchus mykiss), pacu (Piaractus mesopotamicus) and curimbatá (Prochilodus spp.) extracted by slow freezing, as a mechanism to release the lipids of the crude material, and (2) compare the stages of chemical refining (degumming, neu

18. Effects of dietary propolis and vitamin E on growth performance and antioxidant status in blood of juvenile Rainbow trout, Oncorhynchus mykiss (Teleostei: Salmoniformes) under different flow rates
The present study investigated the effects of propolis and vitamin E supplementation in diets of juvenil rainbow trout subjected to two different flow rates with or without flow stress (0.9 and 2.1 l/min, respectively) on final weigth (FW), condition factor (CF), feed conservation ratio (FCR), protein efficiency ratio (PER) and vitamin A, C and E concentrati

19. Comparative mapping reveals quantitative trait loci that affect spawning time in coho salmon (Oncorhynchus kisutch)
Spawning time in salmonids is a sex-limited quantitative trait that can be modified by selection. In rainbow trout (Oncorhynchus mykiss), various quantitative trait loci (QTL) that affect the expression of this trait have been discovered. In this study, we describe four microsatellite loci associated with two possible spawning time QTL regions in coho salmon

20. Using Macrocystis pyrifera (L.) C. Agardh from southern Chile as a source of applied biological compounds
The exploitation of seaweeds in Chile has been carried out for more than 60 years. More recently, seaweeds have been used for the production of alginate, agar and carrageenan, agricultural fertilizers and industrial aquaculture (feed for abalone and sea urchins), increasing the added value of this natural resource. In the Magellan Region (56ºS), the giant k

21. Distribution patterns and trophic characteristics of salmonids and native species inhabiting high altitude rivers of Pampa de Achala region, Argentina
The Pampa de Achala in central Argentina is an area with low fish species richness where salmonids were first introduced at the beginning of the twentieth century. A total of 19 rivers of different order were sampled during the low water period by using portable electrofishing equipment. We covered different identified macrohabitats (pools, riffles, glides a

22. Analysis of the association between spawning time QTL markers and the biannual spawning behavior in rainbow trout (Oncorhynchus mykiss)
The rainbow trout is a salmonid fish that occasionally exhibits broodstocks with biannual spawning behavior, a phenomenon known as a double annual reproductive cycle (DARC). Spawning time quantitative trait loci (SPT-QTLs) affect the time of the year that female rainbow trout spawn and may influence expression of the DARC trait. In this study, microsatellite

23. Prophylactic effect of levamisole on rainbow trout (Oncorhynchus mykiss) against Yersinia ruckeri
Alteration in the relative percentage of survival (RPS) rate of rainbow trout (Oncorhynchus mykiss) exposed to 5, 10 and 25µg ml-1 levamisole for 2 h against Yersinia ruckeri was investigated. The average weight of the 120 fish used in this study was 6.3g. Upon challenge with a virulent strain, the relative survival percentage of respectively 83.3%, 86.7% a

24. Biotecnologia aplicada à salmonicultura
Este trabalho apresenta uma análise conceitual das principais biotecnologias utilizadas na salmonicultura chilena, que é baseada na produção de salmão-do-Atlântico (Salmosalar, 356,407 t), o prateado ou salmão coho (Oncorhynchus kisutch, 116,481 t), (O. tshawytscha, 2,062 t) e truta arco-íris (O. mykiss, 189,178 t).
